The effect of quantity of nutrients on rumen fermentation and the level of metabolic markers in blood serum were simultaneously analysed in groups of dairy cows 21 days before and 21 days after parturition with aim to diagnose disorders in milk production in the transition period of dairy cows. Results of analysis of health disorders confirmed the following: low energy concentration in the diet insufficiently saturated with fibrous carbohydrates, followed with rapid change to concentrate type of diet after delivery resulted in insufficient adaptation of the rumen metabolism before and after rapid transition to production feeding rations after calving; the level indicative of acidification of the rumen environment. Investigation of intermediary metabolism confirmed pre- and post-partum lipomobilization, with increased values of NEFA in 68 % and 54 % of animals respectively, with liver load manifestation in 37 % and 69 % of animals, respectively.

Keywords: lipomobilization, non-esterified fatty acid, rumen, intermediary metabolism
